Added ability to add in new defaults

Is really gross code though, to be honest
Make the recipe edit and delete icons seperate from the title
Added popup and recipe delete validation
Start of the brew in progress page

Uses a lot of similar code to the recipe page. There's a lot of code duplication in this app. There must be a better way...
Start of current brew

Added CSS for current temp and time
Added new brew controller which will take care of the interaction between the brew view and any bluetooth shenanigans that need to take place (well hopefully, I haven't had a real good think about this)
A couple of helper functions have been moved out of the Helper file and into the brew controller
Added count up/down to groups

No implementation of the timer functionality yet
More work on getting the timer to count down

Preliminary, but it works
